s The object of my invention is to provide adevice in which seed cottonin various states of cleanliness can be treated and then assed directlyinto the gins. [It is a well *nown fact that the less the cotton ishandled to put it into condition [or the spinner, the bet ter, since inthe various cleaning operations,

the fiber is apt to got broken, thereby im-- pairing its usefulness.

In carrying out my invention I rovide adevice which is designed to giveeacii batch of cotton coming to the machine a treatment which isespecially adapted for the particular batch being cleaned, and in whichthe treatment may be varied.

My invention is illustrated in the acconn panying drawings, in Which-Figured shows an enlarged gentral vertical section through the cleaner.Fig. 2 is a view of the heaters. Fig. 3 is a transverse section along.the liner 3-3of Fig. 1, looking in the direction of the arrow, and Fig4 is an rior side view of the machine.

Referring now to Fig. 1, A denotes in general an upright box or casing.Leading into the top of this box is a suction pipe B, which communicateswith a feed hopper, not shown. The suction pipe B terminates in adownwardly curved end C immediately above the uppermost heaters. 'l heheaters themselves consist of a series of arms D, mounted on ashaitEc'apable of rotation in the direction indicated by the arrow inFig. 1. There are four sets of these heaters shown in Fig. 1, althoughit is obvious that a greater or less number could be used. The axes ofthe heaters are arranged in an inclined position relatively to eachother and they extend through the l ox l l l tions. The screen extendsfrom the partition F to the bottom G of the box.

Projecting downwardly from the upper part of the box A are thepartitions H an 1, and a screen J extends from the top of the box downto a door K, adjacent to the lowermost set of heaters. The space betweenthe partitions H and 1 forms a curved chute, and at the top of thischute there is a hinged door L, pivoted at k and arranged to swingupwardly into the osition indicated b "the dotted lines, there 3yclosing the pipe and providing an opening into the top of the chntej Asimilar door M is provided and is pivoted at m to swin upwardly into theposition indicated by t e dotted lines and to serve as a deflector toturn the cotton into the chute, which is provided between the screen Jand the inclined wall 0 of the casshown in l -ig. This provides atriangular air duct at the up or end of the casing coininunicating withtie air outlet X. In order to operate the doors M and K sirnuitaneously,l have provided the shifting iever P. This lever is pivoted at Q toacross bar R, the latter being in turn pivoted to an upper laterallyextending arm T of the doord /i, and to a let erally extending arm T ofthe door K. it

in clined screens N and N extend from the top of the casing A to thesides as clearly Will be seen that in the position of the doors K and Min Fig. 1, a downward pull of, the lever will result in opening the doorM and closing the door K. The pull rodUis provided for the purpose ofopening the door L, and this is accomplished through the medium of theextension of the downwardly extending arm V attached to the latter door.

The arranementoi the pulleys for driving the heaters is shown in Fig. 4.It will he seen that the belt W passes over the pulleys a and i), thenunderneath an idler c and over the pulleys d and c, thence to an idlerf. This arrangement provides for driving all of the shafts E in the samedirection.

X indicates the air outlet.

Y and Y are doors, and Z indicates the outlet openingfor the cleanedcotton.

From the foregoing description of the va- Afrorn one side to the other,as shoyvn in fig. l rious'parts of the device, the operation will3,beu1g ournaled in the side walls of the box. .be readily understood.In practice the cot Immediately underneath each set of heaters ton iscarried through the I arrange a curved screen S, having a small hopper,and if the cotton i pi e B from the S l? clearance. ihese screensmeyh'eseparate or mitted to pass through to the end of the pipe 55in onecontinuous screen having curved seeeland be projected downwardly uponthe arms rty, it is per- I carried around rapidly and the dirt therederand behind the b air being scattered 'to pass directly into the Horn isscreened out through the screen S. In passing the screens N and N,anyloose dirt is drawn through the screens, while the cotton isdeflected down the chute. The uppermost beater tosses about the cottonand delivers it to the next heater, which, in turn, subjects the cottonto a similar heating ac tion, and passes it on to the third, and thenceto the fourth, from. which it is finallydelivered through the eXitopening Z into the gin. If, however, a batch of cottonis being treatedwhich does not contain as much dirt, and therefore should not besubjected to the thorough beating which itwill receive by being passedthrough the entire series of heaters, it Y may be deflected downwardlythrough the chute formed by the partitions II and I, by pullingdownwardly on the pull rod U and thereby raising the door L to itsdeflecting position as. shown by the dotted lines in l ig. 1. In thisposition the cotton would be deflected so as to he acted on by the lasttwo heaters only. If, new, a batch should be encountered which it wasdesirable gin, the pull rod P would be operated, thereby 0 ening' the uper door M and closing the ower door thereby passing the cotton directlyinto the gin without subjecting it to the action of the heaters.

It will'be observed that the air space uneaters is large, and the oversuch an area of screen, as indicated by the arrows, allows the heavydirt, sand, trash and other matter to settle to the bottom of thecleaner instead of being carried out through the air outlet. Theprovision of the doors Y and Y allows free access to the interior of thedevice for cleaning purposes. 7

It will thus be seen that I have provided a device in which the cleaningoperation can be varied to suit Wrrious hat .es of cotton by a similararr.-ingement of deflecting doors and levers therefor and chutes tocooperate therewith.

I claim- 1. Ina cotton cleaner, an air pipe, a cleaning chamberconnnunicating there with, said cleaning chamber having downwardlyextending partitions forming chutes, doors at the tops of said chutesarranged to swing upwardly into said pipe and to constitute deflectingmembers, an inclined series of heaters arranged underneath said chutes,a screen underneath said heaters, means for conveying cotton throughsaid of the uppermost set of heaters, where it is I for opena'ir pipe tosaid heaters, and means into said ing said doors to deflect the cottonchutes.-

2. In a cotton cleaner, an air pipe provided with doors in its bottom,chutes communicating with said air pipe, an inclined. series of heaters,means for assing cotton through said air pipe and tirough the entireseries of heaters, and means for deflecting the cotton. through a chuteand thereby passing the latter through only a portion of the series ofheaters.

'3. In a cotton cleaner, an air pipe conveyer, a cleaning chambercommunicating therewith and provided with a downwardly extendingpartition at one side thereof, said partition constituting with theadjacent exterior walla chute, a series of heaters arranged between saidpartition and the opposite wall, a door in said air conveyercommunicatin with the top of said chute, a door at the bottom of saidpartition opening into said chute, and means for simultaneously movingsaid doors to cause the material conveyed by the pipe to pass throughthe heaters or through the chute according to the position of the doors.

4. In a cotton cleaner, a cleaning chamber, heaters arranged therein, ascreen arranged underneath said heaters, an air pi e conveyercommunicating with said 0 amber and arranged to deliver material to saidheaters, a door in said air pipe for deflecting the conveyed materialthrough a portion of the series of heaters, and other means fordeflecting material through the entire series of heaters.

5. In a cotton cleaner, an air pipe convcyer, a cleaning chamber, aseries of heaters arranged in said cleaning chamber, the first of saidheaters being immediately beneath the mouth of said conveyor, a screenfor separating the dirt, means in said air conveyer for deflectingmaterial through certain of said heaters and other means in saidconveyor for deflecting material through the entire series of heaters.

6 In a cotton cleaner, a cleaning chamber provided with heaters andscreens, an air conveyor for delivering material to said heaters, andmeans for passing material from the conveyer at will through the entireseries of heaters or through a portion of the series.
